Preparing the board
Identify parts
Look at the parts you got and make sure you can identify them
Note: we now use different switches and jacks than in the second photo
For resistors, pay attention to the color bands as follows:
100: brown black brown gold
330: orange orange brown gold
1k: brown black red gold
4k7: yellow purple red gold
10k: brown black orange gold
47k: yellow purple orange gold
100k: brown black yellow gold
220k: red red yellow gold
470k: yellow purple yellow gold
1M: brown black green gold
Now look closely at the board diagram. Make sure you know what symbols represent resistors, capacitors, IC sockets, transistors, FETs, diodes, wires, etc..
Drill the holes
Use a dremel and a tiny bit (#60 or #66) to drill a hole on every circle on the soldering side.
www.mouser.com sells the bits, part number 5876-409-66
Make sure to drill 8 or 14 holes for each IC
Periodically check the opposite side to make sure you’re still lined up (hold the drill vertical, not at a slant)
Depending on the IC sockets you have, you may need to ream out the holes for the IC sockets using a thumbtack or a larger drill bit. If your board is too thick (e.g. masonite), you may need to counter-sink the IC socket holes
